Sandel vs Aspen Comparison?

Does anyone have a good comparison of the Sandel 3308 EHSI/SG102 AHRS
combination vs. the Aspen EFD 1000 Pro PFD? The Aspen appears to have
some additional features over the Sandel (backup battery and GPS), but
are they worth the extra cost? Any reliability reports yet?

I haven't looked into these products, but remember that Sandel is a well-established company (founded 1998) and Aspen is an Eclipse Aviation spinoff (founded 2004; started shipping product in 2008). If you're worried about long-term support and reliability, the Sandel should be given the edge.

I decided to go with the Sandel 3308/SG102 combination. And I installed a Castleberry backup electric attitude indicator. I feel I have very similar capability as the Aspen offers. Sandel doesn't charge extra for an HSI in its EHSI. Now in this tight credit market I see Aspen is discounting. Could be good for consumers or could signal financial problems resulting in orphaned units as with the Eclipse (Aspen founders' former employer).

Call me old-fashioned, but I prefer the glideslope indication--next to the CDI indication (Sandel, and classic mechanical HSIs). On the Aspen, the glideslope is next to the attitude indicator.

why not the new SN3500??

Installed Sandel SG102 one month ago to replace Bendix KG102. It failed immediately. The replacement failed after 22 hours -- in solid IFR conditions. (HDG flag dropped and HSI heading rotated at slave speed. Had to shoot no-gyro approach.) Shop is replacing unit presently. I'm not impressed with this system and will likely go back to another KG102.

Sorry you had a negative experience with your SG102. I have been happy with mine. Keeping the software up-to-date has perhaps been the right fix for me. Did you work with Sandel support to resolve your issue?
